Value of cervicovaginal fluid cytokines in prediction of fetal inflammatory response syndrome in pregnancies complicated with preterm premature rupture of membranes (pPROM). J Perinat Med 2020; 48:249-255.

Abstract
Background Preterm premature rupture of membranes (pPROM) is associated with a high risk of prematurity and complications of fetal inflammatory response syndrome (FIRS). The aim of the study is to determine any correlations between the concentration of selected cytokines contained in the cervicovaginal secretion eluates and in the umbilical cord plasma in patients with pPROM and to find the noninvasive markers of FIRS in order to pinpoint the optimal time of the delivery. Methods The study included 80 patients with pPROM between the 24th and 34th week of gestation. The cervicovaginal fluid and umbilical cord blood were collected. Interleukin 6 (IL-6), interleukin 10 (IL-10), interleukin 19 (IL-19) and tumor necrosis factor-α (TNF-α) concentrations were measured in both materials. For the statistical analysis, SigmaStat3.5 software was used. Results There was no direct association in levels of IL-6, TNF-α, IL-10 and IL-19 between the cord blood and cervicovaginal secretions within the studied group. The cut-off point of IL-6 of 26.8 pg/mL in the vaginal fluid had high sensitivity and specificity in order to discriminate between newborns with and without FIRS (81.08%; 76.74%). Conclusion Further studies are needed on a larger group of participants to demonstrate that an elevated concentration of IL-6 above 26.8 pg/mL in the cervicovaginal secretion eluate is an indirect noninvasive marker of FIRS.

Abstract
OBJECTIVES The development of endometriosis is associated with changes in the expression of genes encoding the 3β-hydroxysteroid dehydrogenase type II (HSD3B2) and 17β-hydroxysteroid dehydrogenase type II (HSD17B2), estrogen receptors 1 (ESR1) and 2 (ESR2) and the androgen receptor (AR). However, little is known about the expression of HSD3B2, HSD17B1, HSD17B2, ESR1 ESR2 and AR during the endometrial phases in eutopic endometrium from infertile women with endometriosis. MATERIAL AND METHODS Using RT-qPCR analysis, we assessed the expression of the studied genes in the follicular and luteal phases in eutopic endometrium from fertile women (n = 17) and infertile women (n = 35) with endometriosis. RESULTS In the mid-follicular eutopic endometrium, we observed a significant increase in HSD3B2 transcript levels in all infertile women with endometriosis (p = 0.003), in infertile women with stage I/II endometriosis (p = 0.008) and in infertile women with stage III/IV endometriosis (p = 0.009) compared to all fertile women. There was a significant increase in ESR1 tran-scripts in all infertile women with endometriosis (p = 0.008) and in infertile women with stage I/II endometriosis (p = 0.019) and in infertile women with stage III/IV endometriosis (p = 0.023) compared to all fertile women. In the mid-luteal eutopic endometrium, we did not observe significant differences in HSD3B2, HSD17B1, HSD17B2, ESR1, ESR2 and AR transcripts between infertile women with endometriosis and fertile women. CONCLUSIONS Observed significant increase in HSD3B2 and ESR1 transcripts in follicular eutopic endometrium from infer-tile women with endometriosis may be related to abnormal biological effect of E2 in endometrium, further affecting the development of human embryos.

Abstract
INTRODUCTION The prevalence of endometriosis among reproductive age women is 7-17%; however, these figures reach 20-50% in patients suffering from infertility. Matrix metalloproteinases (MMPs) activity is thought to be particularly essential in the early phases of endometriosis development. Any changes in the equilibrium between MMPs activity and their tissue inhibitors (TIMPs) could be potentially harmful, promoting endometriosis development. The aim of this study was to investigate whether the MMP-2, MMP-9, TIMP-1 or TGF-B2 expression in eutopic endometrium from women with early endometriosis differ when compared with healthy subjects. The results were referred to the serum progesterone levels. MATERIALS AND METHOD Endometrial biopsy was taken from 42 patients (18 in the study group, 22 in thecontrol group) at the time of hysteroscopy for routine histology and for RT-PCR procedures. Comparison of the quantity of gene products was performed with a programme for densitometry and compared to GADPH product, which was a reference value. RESULTS The obtained results did not reveal any statistical difference in endometrial expression of MMP-2, MMp-9, TIMP-1, and TGF-β2 or serum progesterone level between women with endometriosis and without visible signs of this illness. CONCLUSION Despite the lack of statistical differences, it was observed that both examined metalloproteinases expressed a tendency to higher gene expression in the eutopic endometrium of women with endometriosis. However, both TIMP-1 and TGF-β2 expressions had the same tendency - higher values in endometriosis patients.

Abstract
OBJECTIVES Preterm premature rupture of membranes (PPROM) complicates about 5% of pregnancies. Ureaplasma species is the most common pathogen found in the amniotic fluid in pregnancieneonatal outcome. The aim of the following study was to evaluate the impact of colonization with the Ureaplasma spp. on pregnant women with PPROM, coin fection with different microorganisms, and antimicrobial treatment on neonatal outcome. MATERIAL AND METHODS The study included 30 women with PPROM hospitalized in Division of Reproduction in s complicated by PPROM. It is speculated that it requires a coin fection to produce unfavorable Poznan's K. Marcinkowski University of Medical Sciences. Swabs from cenvical canal were obtained for the identifidation of bacterial and ureaplasma tic infections by culture and POR. RESULTS The presence of any infection during the pregnancy a fter PP ROM was con firmed in 22 patients (Ureaplasma spp. in 12 patients, coin fection in 10 women). The cure rate for Ureaplasma species and other infections was 17% (2/12 patients) and 23% (5/22 patients), respectively There was no correlation between Ureaplasma species infection, coin fection, and cure status with the infection in the newborn. The PPROM to delivery duration also did not affect the newborn infection status. A negative relationship with leukocyte level was detected in patient with newborn infection. CONCLUSIONS The presence of colonization with Ureaplasma species is not attributable to neonatal short-term morbidity The evaluation of maternal biochemical and microbiological data, regardless of the duration of the pregnancy after PPROM or the cure status, does not add any insight into the newborn infection status.

Abstract
Introduction. Numerous reports lead to conclusion that either the absence or insufficient amounts of heparanase and heparin binding growth factors on the luminal surface of the epithelium in the endometrium may be associated with impaired reproduction. The aim of this study was to assess the suitability of the fluid from the uterus to predict reproductive disorders. Material and methods. The group consisted of 32 women with 2 or more consecutive unexplained miscarriages, and 33 idiopathic infertility patients; the control group comprised 22 women with normal reproductive potential. Concentration of the studied factors was assayed by ELISA in uterine fluid.Results. The uterine flushings from women with two or more consecutive miscarriages showed significantly lower concentrations of HPA1 (p < 0.001) compared to the control group and infertile patients. In contrast, we didn't observe statistically significant differences of concentration of HB-EGF, VEGF, FGF2 in the studied groups. Statistically significant correlations were obtained between the levels of HPA1 and growth factors in all groups p < 0.05. The ROC curve was used to test the diagnostic value of HPA1. With a cut-off point of 8.56 U/L for HPA1 levels, we achieved 58.6% sensitivity and 84.6% specificity in the detection of women with recurrent miscarriage compared to fertile controls and infertile women combined. The area under curve (AUC) value was 0.751. Conclusions. The procedure for determining the concentrations of HPA1, HB-EGF, VEGF, FGF2 by ELISA in fluids derived from the uterine cavity is insufficient to predict either success of reproduction or reproductive disorders.

Abstract
OBJECTIVES The object of our study was to assess the efficacy measured as achievement of pregnancy of artificial insemination with husband sperm in couples that fulfilled the WHO criteria for infertility. MATERIAL AND METHODS We have identified 120 patients that were diagnosed with infertility defined as at least one year of unprotected intercourse without achieving pregnancy After 2 year follow up the study group comprised 96 women and their partners. All couples had normal outcome of all standard infertility test, except for some with decline in sperm parameters that allowed the husband sperm to be used for fertilization in the IUI procedure according to the 2010 WHO guidelines. After IUI procedure patients were followed either by contact with their physicians, mail questionnaire, or by identification of their national ID number in computerized database of our hospital. RESULTS A total of 32 patients got pregnant (33%). Of those that achieved pregnancy during the two year follow up period, fifteen (46.9%) had done so as a result of AIH, another 15 as a result of spontaneous conception, and two as a result of IVF (6.2%). The mean number of AIH procedures in a group of women that did achieve pregnancy was 3,56 (median 3.0), and was statistically higher than the number of AIH in those patients who have failed to achieve pregnancy (mean 2.54; median 2.0; p = 0.009). CONCLUCIONS: Our study seems to support the new criteria for assessment of sperm parameters. Judging the sperm according to the new, lessened criteria, did produce comparable pregnancy rates as with historical cohorts based on old criteria.

Abstract
INTRODUCTION Claudin-4 (CLDN4) is a transmembrane protein, responsible for cellular contact and organization. A different expression of claudin 4 in the endometrium, depending on the menstrual cycle and with peak at the aim of the 'implantation window', has been observed. CLDN4 is believed to play an important role in embryo implantation. THE AIM The aim of the study was to compare the mRNA CLDN4 expression levels in two subgroups of infertile women (idiopathic infertility or minimal endometriosis) and compare them to fertile controls. METHOD The study included 36 women with idiopathic infertility and 24 with minimal endometriosis. The control group comprised 26 women. Eutopic endometrium samples were collected with a Pipelle device during the implantation window. Firstly mRNA was extracted from the endometrium and reverse transcribed into cDNA. Real time PCR was used for the assessment of relative expression levels. RESULTS The observed transcription level of CLDN4 did not differ statistically between the studied groups, but was significantly higher when compared to controls. CONCLUSIONS Exceedingly high levels of CLDN4 might negatively influence fertility rates.

Abstract
OBJECTIVE Proprotein convertase 6 (PC6) is known to be the key enzyme involved in the transformation of many hormones, cytokines and their receptors into their active forms. Experimental in vitro studies have also proven that lack of PC6 in the endometrium prevents decidualisation. Therefore in our study we have aimed at determining whether infertility in some patients might be attributable to decreased expression of PC6. MATERIAL AND METHODS With the use of RealTime PCR we have studied the expression level of PC6 in receptive phase endometria from 36 idiopathic infertile patients, 26 infertile patients with minimal grade endometriosis and compared those results with fertile, age-matched controls. The endometria were collected 7-9 days after ovulation. RESULTS There were no statistically significant differences regarding the expression of PC6 in endometria from patients with idiopathic infertility, infertile patients with endometriosis and controls. CONCLUSIONS Since there is no detectable difference in PC6 expression, the decreased expression of PC6 is unlikely to cause infertility.

Abstract
During the putative "implantation window", a period of maximal endometrial receptivity that spans 7-9 days after ovulation, a series of changes on the structural and molecular level occur that render the endometrium susceptible to implantation for the human embryo. Many members of the TGFbetas are expressed by human endometrium at different stages of menstrual cycle. Also studies regarding the MMP2 gene expression and activity of MMP2 in the implantation window have shown a higher expression and activity of MMP2 in women with impaired fertility. We have examined by RT-PCR the expression of TGFbeta2 and MMP2, MMP9 and TIMP1 in 28 patients with idiopathic infertility, 16 patients with unexplained recurrent miscarriage and 16 control women were enrolled in this study. Seven to nine days after ovulation endometrial biopsy by Pipelle or hysteroscopy was performed to assess the expression of TGFbeta2 , MMP2, MMP9 and TIMP1. We found that in endometria from women with idiopathic infertility TGFbeta2 expression was 2.8 fold higher than in endometria from control group and 2.1 fold higher in endometrial samples from women with unexplained recurrent miscarriage compared to the control group. The MMP2, MMP9 and TIMP1 expression in endometrial samples revealed no significant differences between the study groups and control group. There was a statistically significant negative correlation between TGFbeta2 and MMP9 expression in endometria from women in control group. The present investigations suggest that dysregulated TGFbeta2, MMP2, MMP9 and TIMP1 expression are associated with infertility and early pregnancy loss. However the exact mechanism of how overexpression of endometrial TGFbetaand MMPs interferes with implantation may be more complex.

Abstract
OBJECTIVE Glycodelin A (GdA) is viewed as a uterine endometrium receptivity marker. The expression of GdA in the endometrium is mirrored in uterine fluid and in the serum. Thanks to its immunosuppressive properties GdA might regulate mechanisms of fertilization, implantation and further development of the embryo. DESIGN The authors assessed the GdA concentration during implantation window of nonconceptional cycles in women with impaired reproduction. MATERIAL AND METHODS Fluid from uterine cavity, serum and endometrial samples were obtained from 116 women, among them 43 have had 2 or more miscarriages, while 52 were infertile. Control constituted 21 fertile women. In uterine fluid and serum the GdA concentration was assessed with ELISA Bioserv Diagnostic kits, and progesterone with electrochemiluminescence. Endometria obtained during hysteroscopy were evaluated in terms of conformity with the cycle dating. RESULTS Statistically lower (p < 0,0001) compared to control GdA concentration in uterine fluid was found in infertile women. The lowest GdA values were obtained in women with idiopathic infertility and infertile women with endometriosis. GdA level of women with 2 or more miscarriages was no statistically significant different compared to control. The lowest concentration of GdA in this group of patients was found in women with luteal phase deficiency. The GdA concentration in the serum was three times lower compared to values noted in uterine fluid, and there was no difference between studied groups. CONCLUSION Based on our research we might conclude that GdA has a more important role during implantation than in further development of the embryo.

Abstract
The objective of this study was to assess the LIF (leukemia inhibitory factor) concentration in uterine flushing and serum (ELISA) of women with proven fertility, infertile women and women with recurrent miscarriage. In addition, progesterone level was determined in serum. A decreased production of LIF in the uterine microenvironment was found in states of impaired fertility. With a cut-off point of 8.23 pg/ml for LIF level in uterine flushings we have achieved 86.7% sensitivity and 100% specificity in detection of women with idiopathic infertility compared to fertile controls. No correlation between LIF in serum and uterine flushing was demonstrated, rendering LIF measurements in serum useless for diagnosis of impaired infertility. We conclude that LIF measurement in uterine flushing could be a useful diagnostic tool to predict unsuccessful implantation.

Abstract
OBJECTIVE To assess the total antioxidant potential of women with endometriosis-associated infertility, women with idiopathic infertility, and fertile controls. DESIGN Retrospective study. SETTING University medical hospital. PATIENT(S) Sixty-five women admitted for diagnostic laparoscopy. MAIN OUTCOME MEASURES Peritoneal fluid samples were analyzed for superoxide dismutase activity and total antioxidant status on spectrophotometry, glutathione peroxidase activity on enzyme-linked immunosorbent assay, and lipid peroxides levels on colorimetry. RESULT(S) Mean activity of superoxide dismutase, glutathione peroxidase, and total antioxidant status was lowest and lipid peroxide level was highest among infertile patients with endometriosis. Women with idiopathic infertility, in contrast, had the highest superoxide dismutase, glutathione peroxidase, and total antioxidant status activity and the lowest lipid peroxide level. CONCLUSION(S) High antioxidant potential is not a contributing factor in women with idiopathic infertility. Low total antioxidant status and low activity of antioxidant enzymes in the peritoneal fluid of infertile women with endometriosis probably do not influence fertility in these women, but these factors may play a role in the development of the disease.

Abstract
OBJECTIVES Endometriosis is characterised as a presence of proliferating endometrial fragments growing outside uterus. Despite many investigations we still do not understand why in some women sheded endometrium implants itself into peritoneum and grows, and in the others does not. It is possible that apoptotic status of endometrial fragments implanted into peritoneum is responsible for endometriosis growth as well as the treatment results. Cellular apoptosis is characterised morphologically by cell shrinkage, nuclear pyknosis, chromatin condensation, and blebbing of the plasma membrane. MATERIAL AND METHODS The study was performed on 28 mature Wistar rats. We studied endometria of rats after induction of endometriosis in peritoneal cavity. RESULTS The only difference was found in endometrial glands. In animals with successful endometriosis implantation apoptosis indices in endometrial glands obtained during second laparotomy were lower than in the endometriosis free animals (p < 0.05).

Abstract
OBJECTIVES The only possibility to diagnose peritoneal endometriosis is laparoscopy or laparotomy with tissue sampling for histology. Women with impalpable endometriosis not visible on ultrasound suffering from infertility or teenagers with pelvic pain, where endometriosis may also be expected, would greatly benefit from an inoperative diagnostic method. A sure and comfortable method of assessing the effectiveness of endometriosis treatment does not exist. The aim of the study was description of the alpha 3 beta 1, alpha 4 beta 1 integrins and beta 1 chain expression in endometrial biopsies in women suffering from endometriosis. MATERIAL AND METHODS Laparoscopy and hysteroscopy was performed in 32 patients because of infertility (n = 23) and/or pelvic pain (n = 11). For histochemical stainings of endometrial biopsy primary and secondary mouse antibodies to human integrins alpha 3 beta 1, alpha 4 beta 1 and beta 1 chain were used (DAKO). RESULTS In 17 women peritoneal endometriosis was diagnosed by biopsy at the time of laparoscopy. An alpha 3 beta 1 integrin was more common in the glandular epithelium of women with endometriosis and beta 1 subunit was less frequently observed in the stroma of the endometriosis group than in women without endometriosis. The differences were statistically significant. CONCLUSION The selected integrins do not yet allow finding a pattern characteristic for endometriosis.

Abstract
Vibrational absorption and circular dichroism spectra of dextrorotatory, levorotatory, and racemic mixture of tert-butylphenylphosphinothioic acid have been measured in CCl(4) solutions in the 2000-900 cm(-1) region. The conformations for both tautomeric structures of (S)-tert-butylphenylphosphinothioic acid are investigated using the B3LYP functional with the 6-31G* basis set. For the most stable conformation, the absorption and VCD spectra are predicted ab initio using the B3LYP functional with 6-31G*, 6-311G(2d, 2p), 6-31+G, and 6-311G(3df, 3pd) basis sets. A different functional, B3PW91, was also used with the 6-31G* basis set. The predicted spectra are compared to the experimental spectra. The comparison indicates that (-)-tert-butylphenylphosphinothioic acid is of the (S)-configuration and exists in only one tautomeric structure and one conformation in CCl(4) solution.

Abstract
Advances in immunohistochemical methods with the specificity of poly- and monoclonal antibodies allow the description of the endometrial receptivity, which is characterized by the ability of secretion of phase specific proteins and glikoproteins by epithelial and stromal cells. We studied the differences in the expression of alpha3beta1, alpha4beta1 and alphaVbeta1 integrins in endometrium of women with recurrent miscarriages and women with unexplained infertility. The endometrial tissue was collected during hysteroscopy performed between 7th and 9th day after ovulation. The immunohistochemical evaluation of alpha3beta1, alpha4beta1 and alphaVbeta1 integrin expression was determined in all endometrial biopsies. Staining intensity of alpha3beta1 in glandular epithelium and endometrial stroma was similar in both groups. In women with recurrent miscarriages we noted a lower concentrations of the alpha4beta1 and alphaVbeta1 integrins during the midluteal phase than in women with unexplained infertility. Moreover, integrins alpha4beta1 and alphaVbeta1 were expressed more frequently in glandular epithelium and endometrial stroma of women with unexplained infertility than those of women with recurrent miscarriages. However, alphaV(2)1 staining in endometrial stroma was stronger than that of alpha4beta1. It can be concluded, that these integrins may play an important role in the implantation process.

Abstract
We studied levels of IL-12 in peritoneal fluid and serum in patients with minimal, advanced and recurrent endometriosis compared to women without endometriotic lesions in pelvis minor. The aim of the study was to determine whether level of IL-12 detected in peritoneal fluid or serum changes with grading of severity of endometriosis. To assess IL-12 levels immunosorbent ELISA was used. There were no statistically significant differences in IL-12 levels in peritoneal fluid nor in serum in any of studied groups. There was higher concentration (without statistical significance) of IL-12 in peritoneal fluid of healthy women compared to women with endometriosis.

Abstract
Alkylation of the alpha-carbanion of (R)-(-)-tert-butyl methyl sulfoxide (4) with n-propyl bromide afforded (+)-n-butyl tert-butyl sulfoxide (1) to which the absolute configuration (R) was ascribed. This assignment was confirmed by X-ray analysis of the complex 6 obtained from the enantiomerically pure sulfoxide (-)-1 and mercury chloride. Vibrational absorption and circular dichroism spectra of (+)-1 were measured in CDCl3 solution in the 2000-900 cm(-1) region and compared with the ab initio predictions of absorption and VCD spectra obtained with density functional theory using the B3LYP/6-31G basis set for different conformers of (R)-1. This comparison indicated also that (+)-1 is of the (R)-configuration.

Abstract
Mid-infrared vibrational unpolarised absorption and vibrational circular dichroism (VCD) spectra of CCl4 solutions of tert-butyl methyl sulfoxide (1) are reported. The spectra are compared to ab initio density functional theory (DFT) calculations carried out using two functionals, B3PW91 and B3LYP, and two basis sets, 6-31G* and TZ2P. The VCD spectra are calculated using Gauge-invariant atomic orbitals (GIAOs). The analysis of the VCD spectrum confirms the R(-)/S(+) absolute configuration of 1. The advantages and disadvantages of VCD spectroscopy in determining the absolute configurations of chiral sulfoxides are discussed.

Abstract
3-(Dimethoxyphosphorylmethyl)cyclopent-2-enone was converted into (+/-)-prostaglandin B1 methyl ester in two steps involving regioselective alkylation at C(2) with methyl 7-iodoheptanoate and subsequent Horner-Wittig reaction with dimer of 2-hydroxyheptanal (42% overall yield). The use of (R)- and (S)-2-(tert-butyldimethylsilyloxy)heptanal for the Horner olefination reaction gave, after deprotection of the hydroxy group, the enantiopure forms of the title compound in 28% overall yield.

Abstract
In tobacco cells, osmotic stress induced the rapid activation of two protein kinases that phosphorylate myelin basic protein. Immunological studies demonstrated that the 48-kD kinase is the salicylic acid-induced protein kinase (SIPK), a member of the mitogen-activated protein kinase family. SIPK was activated 5 to 10 min after the cells were exposed to osmotic stresses, and its activity persisted for approximately 30 min. In contrast, the 42-kD kinase was activated within 1 min after osmotic stress, and its activity was maintained for approximately 2 hr. Moreover, in addition to myelin basic protein, the 42-kD kinase phosphorylated casein and two transcription factors, c-Jun and ATF-2. This latter enzyme was inactivated by a serine/threonine-specific phosphatase but, unlike SIPK, was not affected by a tyrosine-specific phosphatase. After the 42-kD kinase was purified to apparent homogeneity, tryptic peptide analysis indicated that it is a homolog of Arabidopsis serine/threonine kinase1 (ASK1).

Abstract
Daily secretion of pancreatic juice, including postprandial responses to food, was investigated in two groups of calves: preruminant (fed with liquid food) and ruminant (fed with solid food). Male Friesian calves (1 week old and 6 weeks old) were surgically fitted with a pancreatic duct catheter, duodenal cannula and two duodenal electrodes. Continuous 24 h collections of pancreatic juice and myoelectrical recordings were performed with minimal restraint and disturbance of animals. In both groups of calves clear periodic fluctuations in pancreatic juice secretion (volume, protein output and trypsin activity) coinciding with duodenal migrating myoelectric complexes (MMC) were recorded. Secretion of juice per cycle and per day was greater in ruminant calves, but the frequency and amplitude of cycles were lower in this group. There were no differences between day and night-time preprandial pancreatic cycles and duodenal MMC in preruminant calves, whilst in ruminant calves, evening MMC were longer than morning MMC. The pancreatic cephalic phase (increase of volume flow, protein output and trypsin activity during and just after food intake) was significant only in preruminant calves following morning feeding. Postprandial pancreatic cycles did not differ from preprandial cycles, except the pancreatic cycle (juice volume and trypsin activity) in which food was offered in preruminant calves. No gastric or intestinal phase was observed in either group of calves. In conclusion, biological cycles of the gastrointestinal tract are present in both preruminant and ruminant calves, and these cycles evolve along with the change from liquid to solid food.
